STUDY DESIGN: The Pregnancy Risk Assessment Monitoring System
2004e2008 data were analyzed from Missouri, New York state, and
New York City (n ¼ 9536). We used multivariable logistic regression
to assess the associations between prenatal and postpartum contraceptive
counseling and postpartum contraceptive use, defined as any
method and more effective methods (sterilization, intrauterine device,
or hormonal methods).
